The subject has been studied. There is no good evidence supporting that. Cause and effect is not easy to separate and anecdotal evidence is just anecdotal.

People who are not well are known to 'self medicate'.

For example: Increase of alcohol use among people with preexisting problems is well documented. Link between tobacco use and schizophrenia is also well documented. See: "Smoking and schizophrenia" https://pubmed.ncbi.nlm.nih.gov/19794359/ "It has been suggested that smoking may be an attempt by schizophrenic patients to alleviate cognitive deficits and to reduce extrapyramidal side-effects induced by antipsychotic medication."

Psychedelics are not the type of drug people keep using if it harms them. If they don't work for you, you really don't want to do them again.

(ps. I would not recommend _regular_ drug use of any kind)
